What is the order of organs air travels from the mouth to the lungs?

Air travels from the mouth to the lungs through a specific pathway that begins with the pharynx, then moves to the larynx, and finally into the trachea. The pharynx serves as a common passageway for both air and food. It is located behind the mouth and serves as the entry point for air from the nasal cavity and mouth.

Once air passes through the pharynx, it moves into the larynx, also known as the voice box. The larynx functions not only in sound production but also as a critical route that directs air into the trachea while preventing food and other substances from entering the airway.

After passing through the larynx, air enters the trachea, which is a tube that carries the air down into the lungs. The trachea further branches into the bronchi, which lead to the right and left lungs, allowing air to distribute into the lungs for oxygen exchange.

The correct sequence emphasizes the organization of the respiratory system, where these structures function sequentially to ensure that air is properly routed into the lungs for respiration.
